area of field = 3km^2
area of lake = (.9)(.3) = .27 km^2
so, assuming the pilot just flies around randomly till she crashes,
P(lake) = .27/3 = .09
A plane has to crash on the field which is 2km by 1.5km . There is a lake in the corner whose dimensions are 900m by 300 m (i) what is the probability that the plane will crash in the lake
(ii) what is the probability that will crash other than lake.
